Enlistment & war service
After university Morgan became a teacher at Forest School, Forest Rise, Walthamstow, a school with about seventy pupils. This allowed him time to play football. From 1905 he also served with the Territorial Army, Essex Regiment, and from May 1909, the year he started teaching at Repton School, Derbyshire, he was a local captain in the O.T.C.; he appears to have been made a full Captain on 28 September 1910.
A researcher into Welsh international football informed me that during the school summer holiday in 1914 Morgan was on his way to Brazil with Corinthians FC. but on docking in South America the team learned that war had been declared and they sailed straight home with the intention of enlisting. The story within the family was that Morgan had travelled to Wales in the holidays and on the outbreak of war his father had told him to go back and join up, which he did three days later, as soon as the recruiting office opened. Whatever happened, Morgan was quick to enlist and on 5 August 1914 he became a Captain in the 1/4th Battalion, Essex Regiment which had been formed only that month; it became part of the Essex Brigade, East Anglian Division, a Territorial Force Division, which, in May 1915, became 161st Brigade, 54th Division.
